Very neat. Still, I'll be sticking with Sidetrack, and not just because I paid to register it a few weeks ago. For one thing, my Windows and Linux PCs both have keyboards with Synaptics touchpads, so my interface is the same across all three with respect to corner taps, scrolling, etc. (Yes, I actually prefer touchpads to mice.) Secondly, I use the other 3 corner taps for middle click, back browse, forward browse, and it doesn't sound like there's a solution for those in these drivers. The loss of middle click on the trackpad would be huge for me, as I spend a lot of time in X. As for double taps, I never have those kind of problems, so no big whoop there.

All that being said, I'm using this bad boy nowadays, so unless I'm on the go, my Mac mousing/gesture needs are taken care of.
